this will be readily understood when it is remembered that in some' forms of apparatiis valves are not employed in the passageways connecting the retort and standpipe.

What I claim isz- 1. In gas generating apparatus, the coinhination ot' a retort, a stand-pipe, a gas conduit connecting the retort and stand-pipe, a valve for the conduit spaced from the point oi communication hetween the latter and the stand-pipe, and means tor discharging a cooling medium into the conduit iiiterinediate the valve and stand-pipe.

lii gas generating apparatus, the comliiiiation ol a retort, a stand-pipe, a gas conduit connecting the retort and stand-pipe and constantlynopen to the latter, a val've tor the conduit located at the rear end thereof, and means Jor spraying liquid into the conduit intermediate. the valve and stand-pipe.

3. .In gas generating apparatus, they coinhination oi a retort, a stand-pipe, a gas conduit at one end in communication with the retort and inclined downwardly therefrom and at its opposite end in communication with the stand-pipe. a valve lor the conduit spaced trom the stand-pipe end of the latter, and means for discharging 'a cooling inediuminto the conduit intermediate the valve and stand-pipe. p

"L In gas generating apparatus, the lcombination of a retort having a door-closed opening, a stand-pipe, a gas conduit in communication with the stand-pipe and with the retort adjacent to its door-closed opening, a valve for the conduit spaced from the stand-pipe, and means for discharging a. cooling medium into the conduit intermediate the valve and stand-pipe.

l'ii gas gei'ierating apparatus, the comliinatioii of a stand-pipe, a retort and a retort mouth-piece, the latter having a doorclosed opening and an otlsetv located niwardly from said opening' and iii communivatioii with the stand-pipe, a v alre for the conduit spaced from the stand-pipe` and means ior admitting lluid to the conduit hetween the valve and stand-pipe.

A(i. ln gas generating apparatus, the coinliiiiatioii ol' a retort, a stand-pipe, a gas conduit in communication with the stand-pipe and with the retort, and means fe admitting a cooling medium into the conduit.

7. ln gas generating apparatus, the combination of a retort, a stand-pipe, a gas oonvduit iii communication with the retort and stand-pipe and downwardly inclined toward the latter, and means for admitting a coolingmedium into the conduit which drains into the stand-pipehy reason of the inelination of the conduit.

S. In gas generating apparatus, thel coinliiiiation ot' a retort and a retort mouthpiece, the mouth-piece having a door-closed end and a lateral sait-forming ofset adjacent said end, a gas conduit open at one end through the seat-forming surface of the offset and at its opposite end open tothe standpipe, a valve slidalile over the seat-forming surface and adapted toI o'peii and cl'ose the conduit, and valve-actuating means.

9. In gas generating apparatus, the conihiiiation of- .a retort and a iet,oil t,..xnoiith piece, the mouth-piece having a door-lo'sed end and a later-al o'sct formed i#"'ith an inclined seat-forming .face, a s conduit opening through said face ai d linclined downwardly toward and in e'oi inilnication with the stand-pipe, a valve slidable over said inclined seat-forming face and adapted' to open and close the conduit, and valve.
